Captivating and Mysterious: Black Diamond Engagement Rings

Black diamond rings possess a vast amount of symbolism and significance. Their captivating and mysterious black colour encapsulates notions of strength and resilience, serving as a sign of fortitude in the face of life’s trials and tribulations. Within the realm of enduring commitments, like engagements and weddings, these rings assume an even more profound role, representing the unbroken bond between two souls – tested throughout the passage of time.

What are black diamonds?

Black diamonds, also known as fancy black diamonds, are unique gemstones characterised by their deep, opaque colour. Unlike traditional colourless diamonds, black diamonds owe their hue to the presence of numerous inclusions and impurities within their structure – primarily graphite and sulfide. These inclusions scatter and absorb light, resulting in the diamond’s captivating black appearance.

Natural black diamonds are exceptionally rare, making them highly coveted in the world of jewellery. Additionally, there are treated black diamonds, which undergo heat treatments to enhance their colour, and lab-created black diamonds, chemically identical to mined diamonds, but created in a controlled laboratory environment.

Are black diamonds real diamonds?

They certainly are, black diamonds are genuine diamonds, falling into distinct categories. Natural diamonds and carbonados originate organically, formed by geological processes. Natural diamonds develop in the Earth’s crust, while carbonados are thought to have meteoritic origins, composed of carbon, graphite, and diamond.

Treated black diamonds are also discovered in nature but their inherent colour isn’t completely black. Instead, they undergo heat treatment to attain their dark hue, retaining their authenticity as diamonds.

Lab-created black diamonds, conversely, are produced within controlled laboratory environments, not extracted from the ground. While they possess identical chemical and structural traits to mined diamonds, neither their stone nor their colour occurs naturally.

How are natural black diamonds formed?

Black diamonds, also known as carbonado diamonds, have a unique formation process that distinguishes them from traditional white diamonds. While the exact mechanism of their formation is n’ot fully understood, there are several theories:

Inclusions and Graphite: One prevailing theory suggests that black diamonds are formed in regions of the Earth’s mantle where there is an abundance of graphite, a form of carbon. Over billions of years, high temperatures and immense pressure caused carbon atoms to crystallise into diamond structures, with a significant presence of graphite and various impurities. These impurities scatter and absorb light, giving these diamonds their distinctive black colour.

Meteorite Impact: Another theory posits that black diamonds, specifically carbonados, are the result of a meteorite impact. This theory suggests that a high-velocity impact from a meteorite could have caused the intense pressure and heat needed to create these diamonds. The meteorite impact would have forced carbon deep into the Earth’s mantle, where it formed into diamond structures, once again with graphite and other impurities causing the black colour.

Deep Origin: Some researchers believe that black diamonds may originate from much deeper within the Earth’s mantle than traditional diamonds. They suggest that these diamonds form at depths of over 410 miles (660 kilometres) where highly unique geological conditions prevail.

Volcanic Activity: In some cases, black diamonds may be associated with volcanic pipes. These diamonds can be brought closer to the Earth’s surface through volcanic eruptions, although the exact details of their formation in this context are still under study.

Each one of these theories is highly fascinating and adds to the mystery and appeal of these most secretive of stones.

Do black diamonds demand a high price point?

The cost of black diamonds varies based on several factors. Natural black diamonds, known as fancy black diamonds, are typically among the most expensive due to their rarity and unique inclusions that create their colour. Carbonados, another type of black diamond with a meteoritic origin, can also command high prices.

On the other hand, treated black diamonds are often more competitively priced compared to natural black diamonds, because they undergo a heat treatment process to enhance their colour. This makes them more accessible to a wider range of price points. Lab-created black diamonds, grown in a controlled environment, generally sit on a lower price scale than both natural and treated black diamonds.

The size (carat weight) of the black diamond also plays a significant role in determining its price, with larger stones typically valued higher than smaller ones. Ultimately, the amounts black diamonds demand can vary widely depending on their type, size, and origin, making it possible to find many kinds of black diamonds that suit different price preferences.

Is a black diamond suitable for an engagement ring?

Absolutely, black diamonds can make for a striking and unique choice of engagement ring, and have gained popularity for their bold and distinctive appearance. Their deep, mysterious colour sets them apart from traditional white diamonds, making them an excellent option for those seeking an alternative and unconventional ring.

Black diamonds can be used as the centre stone or as accent stones, depending on the design, and they can be set in various metals, from classic white gold and yellow gold to more contemporary choices like rose gold or platinum. Their versatility allows for a wide range of designs to match individual preferences.

However, it’s essential to consider personal taste and style when choosing a black diamond for an engagement ring, as they may not suit everyone.

What do black diamond rings symbolise?

Black diamond rings carry profound symbolism and meaning. Their deep, enigmatic hue embodies strength and resilience, serving as a powerful symbol of endurance and the capacity to conquer life’s challenges. This symbolism is significant when thinking about a lifelong commitment, and the engagement or wedding ring representing it. The durability of the diamond mirrors that of the bond between two individuals that endures over time.

Moreover, black diamonds epitomise sophistication and individuality. Their unconventional allure challenges conventional norms, signifying a departure from the ordinary and a celebration of uniqueness. They appeal to those who cherish non-conformity and possess a distinctive sense of style, making a bold statement about their personality and stylistic preferences.

Celebrity black diamond rings

Black diamond rings have made their mark in the world of celebrity jewellery, adding a touch of intrigue and uniqueness to the red carpet. Here are a few notable celebrity black diamond ring moments:

Carrie Bradshaw (Sarah Jessica Parker): While fictional, the character Carrie Bradshaw in Sex and the City sported a memorable black diamond engagement ring when Mr Big proposed. This iconic ring set the trend for unconventional engagement rings

Carmen Electra: The actress and model received a black diamond engagement ring from rocker Rob Patterson, describing the design as “different – it’s our style.” The ring featured a stunning black diamond centre stone surrounded by a halo of smaller white diamonds.

Other celebrities who have worn black diamond jewellery include 90210 actors Sheane Grimes-Beech and Jennie Garth, singer Katy Perry and makeup mogul Kat Von D.

Debunking misconceptions about black diamonds

Black diamonds, also known as carbonado diamonds, often come with misconceptions due to their unique appearance and characteristics. Here are some common fallacies about black diamonds debunked:

Not Real Diamonds: One prevalent myth is that black diamonds are not real diamonds. In reality, they are genuine diamonds with the same carbon crystal structure as traditional colourless diamonds. Their black colour comes from a level of inclusions and impurities that aren’t typically seen in white diamonds.

Inferior Brilliance: While black diamonds do not exhibit the same sparkle as white diamonds due to their colour, they have a unique and captivating lustre. When properly cut and polished, they can still radiate a beautiful glow.

Fragile: Black diamonds are often thought to be more fragile than white diamonds. However, their hardness on the Mohs scale is similar to that of white diamonds, making them durable and suitable for everyday wear.

Limited Availability: While black diamonds are rarer than white diamonds, they’re not as scarce as some believe. They’re available in various sizes and shapes, and their popularity has led to increased production.

Shouldn’t Be Used for Engagement Rings: Black diamonds have gained popularity as engagement rings, proving that they can symbolise love and commitment just as effectively as white diamonds. They offer a unique and opulent choice for those seeking non-traditional rings.

They’re Treated to Be Black: While some black diamonds undergo heat treatment to enhance their colour, many black diamonds are naturally black due to the presence of inclusions and impurities. It is also important to note that most coloured gemstones often go through the heat treating process to enhance their colours as well. Rubies, sapphires and emeralds all fall into that category, and it’s not something that takes away from their quality or desirability at all.


The world of black diamond engagement rings offers a captivating fusion of edge, style and uniqueness. These enigmatic gems, while challenging conventional norms, symbolise love, strength, and individuality in profound ways.
